first prototype PCBs for MNT RCM4 are here. unfortunately made a mistake and ordered 1.6mm thickness, but good for pre-testing. MNT RCM4 will enable the use of Raspberry Pi CM4, Pine SOQuartz, intergalaktik ULX4M and others in MNT Reform.
i guess the tricky bit with something like this as a virtual world system is uhh. with sprite work you can't really reorient your furniture all that well.
although its possible to perspective shift it some
might be tricky to make the sprites properly so you can move them around inside the rooms
